troubleshooting – needle-like texture on the entire film after development. PF4.

I'm developing a backlog of black and white movies because I do not have access to my darkroom for a while. I do Fp4 – 120 – taken with a Yashica and developing in the same tank using Rodinal / modern equivalent. Everything is fine, 8 films are made (fresh each time) when one of the two films comes out with thin veins tone throughout the length of the film. At first glance, the negatives are good, the ribs are subtle. I have been developing my own movies for a long time, but I have never seen it. I do not want it to happen again when did it happen here? This film in particular waited 2 years to be developed, the other Fp4 present in the tank was "cooler".
